SECURING MEANS FOR VEHICLE-TIRES.

Application filed January 13, 1913. Serial No. 741,675,

To aw whom it may concern:

Be it known that 1, MAX CYRUS OVERMAN,

"a citizen of the United States, residing'at ,New York, in the county of New York and State ofNew York, have invented certain new and useful Improvements 1n Securing Means for Vehicle-Tires, of which the following is a specification.

My present invention relates to improvements in securing rubber tires to vehicle wheels,'and by this is meant tires of rubber,

arubber composition, or a rubber substituteor equivalent.

M invention is es )eeiallv valuable for use inconneetion with cushion tires like those of my own invention, which sustain the load by vertical compression of their side walls with accompanying thickening but without bending collapse. p

The objects and advantages of my invention will appear to those skilled in the art from an understanding of the following description'in connection with the drawings.

vThese show for purposes of illustration, only one of the specific embodiments which my invention is adapted to take.

In them, Figure 1 is a side elevation of a wheel and the provided with my improved securing means,'only .four of which, however,-are shown, it being understood in prac two that s1m1lar securlng means will be providedclamping the tire to the wheel periphcry all the way around the wheel; Fig; 2 is a radial section through the tire, folly and telly-band of the wheel in Fig. 1, on an enlarged scale, the parts being shown in the position assumed whenthe tire is clamped to the wheel; Fig. 3 is :1 section of the same tire shown in Fig; 2 detached from the wheel; Fig. 4: isa perspective View on an enlarged scale of one of the clamping devices; and Fig. 5 is a view of one of the staples hereinafter described.

I will now describe the specific devices of the drawings, reserving it to the claims to point out the novel features and to define the scope of the invention, it being understood that the claims Will be given the due range of equiva'lents'to which they may be entitled in view of the art.

3 is the folly of a vehicle wheel having spokes 2 and an encircling metal telly-band or rim 4.-

tions l3, l3.

5 is a tire of my own invention having thick, substantially straight side walls which steeply converge to a deep nose portion 7 having a wlde bottom 8 which givesfirm ground, support for the tire immediately under its walls. Further, the tire has a longitudinal opening 9 through it with a smell triangular cross section inclosed by said walls and nose portion.

10 is a longitudinal tread groove under the longitudinal opening 9 crossed at intervals by transverse webs 11, one of which is shown in elevation in Flgs. 2 and 3.

12, 12 are transverse grooves or cuts extending from the tread and the tread groove upwardly under the side walls 6 and outwardly through the sides of the nose portion- 7 near the tread. The side walls ,6'have at their base lnwardly extending clamping por- The expressions over, and the like occurring in the description and claims refer to the section of the tire when positioned as in Fig. 2. v

14 is an inside clamping plate shown in end view; and 15 is bolt means extending through a hole in the wheel periphery for drawing said plate toward said periphery to compress and clamp the tire ortions 13, 13 against it. T] 's they do an :estrictedly and thereby tend to draw the material of the side walls of the tireinwardly toward the triangular opening and correspondingly prevent the outer portions of the tire from bulging outwardly toward and under the flanges. It will be unclerstoodthat there are a plurality of the" clamping plates Hand connected bolt means 15 located in sufiicient number all around the wheel-periphery to secure the tire properly thereto.

' 31, 31'represent projections, preferably rectangular in plan view on the outer side of the telly-band fitting intoeorresponding recesses 32 in the base of the legs of the tire whereby the drive is delivered from the folly and felly-band directly overthe legsofithe tire and whereby restricted necks informed The walls ti, 6 at their base have outwardly extending clamping portions 16, 16. These in their normal or uncompressed condition in the illustrated tire (see Fig. 3) are each partially separated from its own side of the tire by an upright space 17 extending toward the telly. Each of these clamping portions 16 is pierced by a plurality of longitudinally spaced radial holes 18 having relatively short and incompressible, preferably metal, tubes 19 seated or molded therein next the base of the tire. 'The idea is to provide a sufficient depth of material belonging to the clamping portions 16 below each tube 19 to be compressed by the clamping means 20 to bind the clamping portion 16 securely to the wheel-periphery, with the tubes 19 acting as a stop to limit the extent of the compression so that it does not drag or draw. outwardly or seriously distort the material of the sides of the tire.

21 is a circumferential bead on the underside of the clan'iping portion 16 which the clamping means 20 hook around as'shown in Fig. 2 to bind the tire all the more securely to the wheel.

The illustrated clamping means 20 conof a plurality of stems 22 extending through the tubes 19 and through corre-- sponding holes in the felly and Telly-band. The inner ends of these stems are threaded and fitted with nuts and washers 23. The outer ends have a right angled extension or cross-piece :24; (Fig. 4) located within the fold 27) of the bent up piece of sheet metal constituting the plate or head portion 26 of each clamp. Each of these plates 26 is bent to have a part 27 at the side of the clamping portion 10, and further has a foot adapted to contact with the telly-band and to be secured thereto when said clamping portion has been suliicicntly compressed.

After the clamps 20 have been tightened by means of the nuts :23 to properly secure the tire to the wheel, I prefer to secure their foot portions more or less permanently to the fell vband. For this purpose, I provide holes :29 through each foot portion corresponding with similar holes through the projecting rim 4 on the folly. Further, I provide wire staples 30 whose legs are passed upwardly through these holes and are then clenched down against the top of the rim 4. In case anything requires the removal of the tire. it is a simple matter to cut off the riveted heads of these staples, whereas meanwhile the attachment of the tire to the wheel is perfectly secure.

It will be noted that the clamps 20 constitute a'se ctional wheel flange and that if any one or more of them become battered or damaged, it can be replaced without disturbing the others.

What I claim is:

1. In combination. a wheel, a rubber tire having at its sides outwardly projecting basal clampingportions which. when uucompressed, are part ally separated from the side of the tire by an upright space c.\'-

In combination. a wheel. a rubber tire having at its sides outwardly projecting basal clamping portions. a plurality of lUIlgl-Llldlnally spat-ed relatively incompressible tubes" extending radially outward through the clamping portions for 'part of their depth,

and a plurality of clamping means com pressing the clamping portions toward the wheel-periphery, each comprising a head and a stem, the head engaging the clamping portion, andthe stem passing through the clamping portlon and one ofthe aforesaid I tubes and engaging the wheel.

3.-In combmat1on,a wheel, a rubber tire having at its sides outwardly projecting basal clamping portions. a plurality of Iongitudmal l y spaced relatlvely lncompressible tubes extending radially outward through the clamping portions for part of their depth, and a plurality ;of clamping means compressing the clamping portions toward the wheel-1ieriphery, each comprising a bolt extending bolt beyond the clamping portion, said plate extending laterally to the edge of the clam ing portion and thence inwardly at the si e' of the clamping portion and having a foot "from thewheel through one of: the tubes. and a platoon the end of said adapted to contact withthe wheel when the a clamping portion has been compressed, and means for connecting said foot to the wheel.
